SHAPE-METAL-I-CUITTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 528,738, dated November6, 1894.

Application filed March 5, 1894. Serial No. 502,314. (No model.)

To all whom it may concern.-

Be it known that I, LEROY S. PFOUTS, a citizen of the United States,residing at Canton, in the county of Stark and State of Ohio, haveinvented certain new and useful Improve,

mentsin Shape-lVIetal-CuttingMachines;and;

I do hereby declare that the following isa full,

. the parts taken or broken away being indicated by the dotted line X X,Fig. 2. Fig. 2, is a horizontal section through line y y, Fig. 1. Fig.3, is a transverse section of the guides and a top view of the presserblock, showing transverse section of the presser block, connecting andoperating bars. Fig.4., is a transverse section of the bed, showing thelower dies placed in proper position.

The present invention has relation to shape metal cutting machines, andit consists in the different parts and combination of parts, hereinafterdescribed and particularlypointed out in the claims.

Similar letters of reference indicate corresponding parts in all of thefigures of the drawings. v In the accompanying drawings A, repre sentsthe bed or base of the machine proper, which is preferably formed ofa'single piece of casting, and of sufficientsize and weight to give tothe machine the desired amount of strength and rigidity for the purposedesigned. Upon the top or upper portion of the bed A are located theupright guides B, which upright guides may be substantially of the formshown in Fig. 3 in cross section.

The upright guides B, may-if desired be cast with the bed A, or ifdesired, said upright guides may be formed separate and securelyattached a to the bed, in any convenient and well known manner. To theupright guides B are securely attached in any convenient and well knownmanner, the piston cylinders. O, D and E, which piston cylinders arepreferably located in a true vertical line, as illustrated in Fig. 1.

Within the piston cylinders C, D and E, are located the pistons a b, andc, to which pistons are attached the piston rods d, d and d To thebottom or lower end of the piston rod d is securely attached the slidinghead F, to which sliding head are securely attached the connecting rodsG, which connecting rods extend downward, as illustrated in Fig. 1, andto their bottom or lower ends is securely at' tached in any convenientand Well known manner the presser block H. To the bottom orunder side ofsaid presser block is securely attached the head I, which head is heldin proper position by means of the lug bolts e or their equivalents.

The object and purpose of holding the head I to the presser block H, bythe lug bolts e, is to provide for easily removing the head I, so as tosubstitute various sized and shaped heads, so as to conform to varioussized and shaped I beams or channel bars.

Directly below the presser block H and its head I are located the lowerdies f, which dies are securely fastened to the bed A, by means ofsuitable lug bolts or their equivalents. For the purpose hereinafterdescribed the opening J is provided, which opening is located betweenthe inner faces of the dies f.

To the bottom or lowerend of the piston rod d is securely attached thehead K, to which head is securely and rigidly attached the webcuttingblade K, which cutting blade extends downward through the presserblock H, and t hehead I, substantially asillustratedinFig.1.

.The flange cutting blades L, are located in the grooves L, whichgrooves L are so located with reference to the flanges of an I beam orchannel bar, when said Ibeam or channel bar is placed in the positionillustrated in Fig. 1, that the cutting blades L, will come directlyopposite the flanges of the I beam or channel bar.

To the outer ends of the flange cutting blades L, are pivotallyconnected the links g, to which links are pivotally connected the bottomor lower ends of the levers M, said leversM being pivotally attached tothebed A, or its equivalent by means of the cross-bolts or bars h, ortheir equivalents. The levers M extend upward, substantially as shown inFig. 1, and to their top or upper ends, are pivotally connected the barsN; the top or upper ends of said bars being pivotally connected to thehead 0, which head is securely attached to the bottom or lower end ofthe piston rod d.

In use the bar or beam designed to be cut is placed in the positionillustrated in Fig. 1, which position brings the bar directly over thediesf, after which the lever A is turned or moved, so as to open thepipe A and thereby allow water to enter the top or upper end of thecylinder D, which in turn forces the piston cl downward, and firmlyclamps the bar designed to be out between the head I, and the top orupper edges of the bed A or blocks placed by the side of the dies f.After the I beam or channel-bar is clamped as above described, the leverA is turned or moved so as to open the pipe A thereby allowing the waterto enter the cylinder E above the piston c, which forces the head K,together with the cutting blade K downward, and. through the web of an Ibeam or channel-bar. After the cutting blade K has been forced downwardand made its cut, the lever A is moved in the opposite direction, whichopens the pipe A thereby allowing water to enter the cylinder E belowthe piston c, which elevates the cutting blade. After this is done,(thatis to say, the cutting blade K is elevated) the lever A is moved soas to open the pipe A thereby allowing water to enter the top or upperend of the cylinder 0, which forces the piston rod d, together with itshead 0 downward, thereby forcing the top or upper ends of the levers Moutward, by means of the bars N, which in turn forces the bottom orlower ends of the levers M inward, or toward each other; causing thecutting blades L, to be moved horizontally toward each other and againstthe flanges of the beam designed to be cut.

When it is desired to elevate the presser block H, together with thehead I, the lever A is turned so as to open the pipe A thereby allowingwater to enter the cylinder B, below the piston, and elevate saidpiston, and the different parts attached thereto, thereby releasing theI beam or channel-bar aftera complete out has been made.

It will be understood that the diesf, are to be tapered at their ends soas to allow the flanges of the beam to be placed against the ends ofsaid dies. It will also be understood that notches are to be formed inthe bed A, or blocks for the purpose of receiving the lower flanges ofthe beam designed to be cut.

It will be understood that the presser block H, should be formed withthe opening B, which opening allows a reciprocating movement to be givento the cutting blade K independent of the movement of the presser blockH.

The head I is preferably formed in two pieces, and the pieces set ashort distance apart so as to allow the cutting blade K to move up anddown between the head; but it will be understood that the head I, may beformed of a single piece, and the ends a separated or grooved for thepurpose hereinafter described.

It will be understood that the ends a of the head I, are to act as dies,for the purpose of cutting the upper flanges of-the I beam orchannel-bar, and that the ends of the diesfact as dies for cutting thelower flanges of the I beam or channel-bar.

The object and purpose of setting the ends a? of the head I a shortdistance apart, or 1n other words forming a space or groove upon the endof the head I, is to allow the cutting blades L to be moved horizontallythrough the flanges of an I beam, without allowing the cutting end ofthe blades L to comein contact with the ends of the head I.

It will be understood that when it is desired to move the cutting bladesL from each other, or away from the flanges of an I beam or channel-bar,the lever A, is to be moved or turned so as to open the pipe A therebyallowingwater to enter under the piston a,which elevates said piston,and draws the top or upper ends of the lovers M toward each other, andthe bottom or lower ends of said levers away from each other.

It will be understood that the valve chambers O are each to be providedwith two way cocks so located that one movement of the different leversA, A and A, will open and close the respective pipes, attached to thedifferent valve chambers. The construction of the valve chambers 0 maybe varied, as their only object is to supply water to the differentcylinders as above described.

It will be understood that hydraulic pressure is to be brought about inthe usual manner, which is common and well known.

It will be understood that I do not desire to be confined to waterpressurealone, as it will be understood, that my machine can be operatedwith any kind of pressure brought to bear against the various pistonswithin the cylinders.

Having fully described my invention, What I claim as new, and desire tosecure by Letters Patent, is-- 1. In a shape metal cutting machine, abedand fixed dies, a vertically reciprocating cutting blade, a presserblock provided at its bottom or under side with a head, horizontallymoving cutting blades, and means for operating the horizontally movingcutting blades, substantially as and for the purpose specified.
